...Wow. S-so you... you was part of Van Zieks and the Baskervilles' family all along...? Cor... That's gotta be a lot to take in.

[It feels like a lot just to her, and she's not the one actually related to them!]

I- I'm sorry that your pa, that 'e... that 'e's already... gone. [She sniffles. Also sorry that he was a murderer too, but it feels particularly bad that the quest to find Iris's father has led to someone long dead.]

Oh Iris...! [She tries to pull her into a hug.]
